The Multiquip 505196 is a genuine OEM Carriage Bolt 3/8 NC X1-1/2 G5 designed for Essick and Whiteman mixer series equipment including the EM70P/S, EM90P/S, WM45H, WM45HCE, WM45HE, WM63E, WM63H5, WM63H8, and WM63SLF. Sourced directly through Multiquip's authorized parts network, this Grade 5 fastener meets the original engineering specification for these mixer platforms. Correct fastener grade and thread spec matter — using an undersized or off-grade substitute can compromise structural integrity at critical joints. Confirm your model against the fitment list above before ordering.
Key Features
- Grade 5 Tensile Strength — Rated G5 for the load demands of mixer drum and frame mounting points, where fastener fatigue is a real failure mode.
- Correct Thread Specification — 3/8 NC (National Coarse) thread form matches the original tapped holes and mating hardware on these mixer models without re-tapping or modification.
- Broad Mixer Fitment — Verified for Essick EM70P/S and EM90P/S plaster/mortar mixers and Whiteman WM45H, WM45HCE, WM45HE, WM63E, WM63H5, WM63H8, and WM63SLF models.
- Genuine OEM Part — Supplied as an authentic Multiquip component, ensuring the fastener head profile, shank diameter, and length match the original hardware exactly as assembled at the factory.
- Structural Joint Integrity — A properly torqued, correctly graded carriage bolt keeps drum brackets, handles, and frame components securely seated through the continuous vibration loads of mixer operation.
A carriage bolt is a through-fastener designed with a smooth, domed head and a square shoulder beneath it that bites into the material being clamped, preventing the bolt from spinning while a nut is tightened from the opposite side. On concrete and mortar mixers, carriage bolts are used at high-stress structural joints — drum brackets, frame rails, and handle assemblies — where the round head profile reduces snag points and the square shank lock resists loosening under vibration. When a carriage bolt stretches, strips, or shears at these joints, connected components can shift or separate, causing uneven drum rotation, excessive noise, or unsafe machine movement during operation.
